FLOWSIC900 is the result of our many years of experience in natural
gas measurement: a flowmeter specially tailored to the requirements
of the LNG industry. It offers the required custody transfer
accuracy for volume flow measurement and meets highest metrological
standards. With FLOWSIC900 and the proven products FLOWSIC600-XT
and FLOWSIC100 Flare-XT, we offer high-end measurement solutions
from a single source to bring measurement performance and
reliability in LNG plants to a new level.
Custody transfer measurement of LNG
On- and offshore applications
Liquefaction, transport and storage of LNG
Device properties:
Intrinsically safe and reliable ultrasonic transducers
Conform to OIML R117 Cl. 0.3 and API MPMS Ch. 5.8
Real time measurement and diagnostics
Full bore design without pressure drop or need for flow conditioner
Factory thermal pre-insulation
Remote Signal Processing Unit" "Benefits
Low measurement uncertainty directly at custody transfer point
reducing financial risks during LNG-transaction
Increased transparency during LNG transaction by dynamic &
real-time measurement &
diagnostics
Operational expenditure savings by reduced boil-off gas losses and
efficient LNG transfer due to minimized pressure drop
Capital expenditure savings by simpliefied meter integration and
installation due to compact design and factory pre-insulation
Easy and fast access during commissioning and regular checks with
remote SPU" "Measuring principle
